No, not that Manhattan, but an important part of history related to the Manhattan Project is a little-known beach and former home located on the north shore of St. John.  If this is your first trip to St. John, go to the other wonderful beaches.  If you're a bit of a history buff or have explored many of the jewels on this marvelous island already, consider a detour that is really off the beaten path to the former home of J.Robert Oppenheimer. 

Oppenheimber Beach Gate

Find this beach by driving slowly past Hawksnest and watching for the short driveway to the gates (open) on the left.  This is about .3 miles past the Hawksnest Bay turn.  It's also called Gibney Beach for the original family who built there.  The Gibneys sold the northern portion of their land to J. Robert Oppenheimer, "father of the atomic bomb," and the director of the Manhattan Project of Los Alamos, NM.  He apparently found rest, relaxation, and escape from American politics during the late 1950's right here.former Oppenheimer home, now a community building

In the long but excellent biography, American Prometheus:  Triumph and Tragedy of J. Robert Oppenheimer, by Bird and Sherwin, you can read about the disagreements that evolved between the Gibneys and the Oppenheimers and the tragedy of his daughter, Toni's, suicide in the house which is now a yellow community center given to the people of St. John.  You'll also learn that his widow chose to drop the urn containing Oppenheimer's ashes off the beach in deep water.

 This is a bit of unexpected history on the idyllic island of St. John.
